Description
Technical field
The present invention relates to herbicide technology field, and in particular to a kind of glyphosate containing cycocel with synergistic activity
Class Herbicidal combinations.
Background technology
General glyphosate turns into the most important herbicide in the world with its wide spectrum, environmentally friendly and low toxicity, due to its tool
There is particular mechanism of action, causing weeds to produce it, resistance is very slow, from 1974 extensively using between 20 years in 1993,
The never report on glyphosate-resistant weeds.But after 1996, with a series of transgenosis glyphosate resistant crops
Expand plantation, revolutionize the conventional use pattern of glyphosate, start it is single and before crop sprout and after sprouting etc. no
Repeatedly used with growth and development stage, glyphosate is using more prevalent, and consumption is dramatically increased, and glyphosate is used for multiple times every year,
No-tillage area is caused to expand.Depending on unduly and being used for a long time for same mechanism of action herbicide, will certainly cause weed control
Fall transition and produce resistance, under selection pressure effect, weeds produce resistance or patience to it and will significantly increased.It is careless in recent years
Sweet phosphine faces enormous challenge and pressure.
First, weeds generate resistance to glyphosate.In the high intensity selection pressure of long-term substantial amounts of use glyphosate
Under, 28 kinds of resistance glyphosate weeds are found that in the farmland of multiple countries and regions, the weeds such as particularly common lamb's-quarters and amaranth are fast
Fast resistance rapid development.China also occur in that many ivy glorybinds showed glyphosate in resistant weeds, such as North China wheatland,
The dominant weeds such as field bindweed, wartwort, the Conyza canadensis of Ningbo of Zhejiang etc., field thistle, meadow pine, lettuce pod dish in orchard etc. are perennial miscellaneous
Grass, it is no longer sensitive to glyphosate.
Secondly, significant changes occur for weed community.Weeds are under the selection pressure of glyphosate, although weeds are to glyphosate
Resistance is continued to develop, but because different weeds have difference to glyphosate-tolerant, therefore weed population changes specific resistivity bion
Frequently become apparent from.Such as continuous application glyphosate more than 3 years, in sweet potato field, Conyza canadensis, thorn lettuce, summer cypress, Siberian cocklebur amaranth, lamb's-quarters,
Salsola collina etc. is increased, and in cotton field Soybean Field, the annual grassy weeds such as amaranth, dayflower, knotweed, sweet potato, green bristlegrass, piemarker and nutgrass flatsedge turns into
Main weeds.
3rd, the increase of controlling weeds unit dose.Glyphosate bioactivity is high, and consumption is low, and price and unit area are used
Cost is low, is one of its sales promotion and the advantage used.Dosage under normal circumstances, orchard, plantation spray active ingredient 50
~100 grams/acre, farmland sprays 20~80 grams/acre of active ingredient, forestry, road, garden or wasteland spray active ingredient 75~
200 grams/acre, add water 15~40 liters, dilute 200~300 times of sprayings.But in recent years, frequently using with glyphosate, causes miscellaneous
Grass increases the patience of glyphosate, and present dosage reaches original 3~8 times, dilute even more than more than the 8 of normal usage times
Release multiple and be reduced to less than 100 times.By taking 41% glyphosate isopropylamine salt water solution as an example, original every mu of 150~300 milliliters of consumption,
Present every mu of 200~900 milliliters of consumption.
In addition, in production application, due to glyphosate, herbicidal effect is reduced under conventional formulation rate, in order to improve grass
The herbicidal effect of sweet phosphine, user increases consumption arbitrarily with other herbicides or non-farm chemical ingredients mixture, arbitrarily, changes user
Method etc., the problems such as causing crop poisoning, person poultry poisoning, pollution environment, effect difference occur occurs often.
